对堤脚失稳造成的堤防滑坡险情案例，通过地质勘察、数值模拟等方法查清了滑坡的原因，查明了滑动体范围，提出了防止这类滑坡的有效方法：①堤防发生滑动后，应尽早完成滑坡带的测绘工作，并提请专业单位或专家研究处理方案，切不可盲目处理；②滑坡处理应着重放在提高堤脚土体的抗剪强度上，以提高堤脚的顶托能力；③对于浅层和原因明确的滑坡，可以简化地质勘察程序，对于地质条件复杂或未进行地质勘察的深层滑坡，应进行地质勘察，进一步查清滑动带范围并分析滑动原因；④工程建设时应尽量避免堤脚临空筑堤或进行沟槽开挖。

As an example that the embankment landslide danger posed by dike foot instability,the reasons of embankment landslide were found through the geological investigation and numerical simulation method,the range of sliding body was determined and the effective methods to prevent such landslides were presented. The results show that:a)After the dike sliding,the work of surveying and mapping of the landslide zone are com-pleted within a short time,and the treatment scheme of specialized units or expert are put forward;b)The shear strength of soil is improved in the landslide treatment in order to improve the ability of the foot support;c)Geological investigation program are simplified for the clear shallow and causes of the landslide,for the complex geological conditions or not deep landslide geological survey the geological prospecting should be carried out,the sliding zone is further investigated and sliding reason is analyzed;d)The desired effect is difficult to be achieved through a single treat-ment measure means of instability caused by the landslide;e)The dike foot air building at the embankment and trench excavation during construc-tion should be avoided.
